Indianapolis Colts quarterback Anthony Richardson has been downgraded to doubtful for the upcoming game against the Jacksonville Jaguars due to an oblique injury sustained in last week's victory over the Pittsburgh Steelers. Veteran backup Joe Flacco is expected to start in Richardson's place, having performed well in relief last week. The Colts are also dealing with multiple injuries to key players, including center Ryan Kelly and star running back Jonathan Taylor, which could impact their performance against the Jaguars.

• Richardson's injury raises concerns about his durability as he has missed 13 of 21 games since being drafted.
• Flacco's experience may help stabilize the Colts' offense despite the injuries to key players.
